33. Mark is a graduate student studying the function of a gene called X in neurodevelopment in Drosophila. In the mutant animals without X gene, the transportation of synaptic vesicles is abolished. He did research on protein sequence of X, and found that there is a nuclear localization sequence. He cloned the gene and confirmed the subcellular localization of X protein. Based on it, he predicts that the function of X is unlikely to be:
(A) a histone
(B) a transcription factor
(C) a factor in spliceosome
(D) a mitochondria protein
(E) a DNA polymerase
